50 MHz Cortex-M3 with CANbus — what this part delivers
The LM3S2432-IQC50-A2: This is a Stellaris ARM Cortex-M3 32-bit single-core MCU clocked at 50 MHz, with 96 KB Flash and 32 KB RAM. It carries CANbus, I²C, IrDA, Microwire, SPI, SSI, and UART/USART connectivity, plus three 10-bit ADC channels and 34 general-purpose I/O.
50 MHz core — timing margin for control loops
At 50 MHz, this Cortex-M3 executes single-cycle multiply and hardware divide, giving deterministic interrupt latency for motor-drive or CANopen node firmware. The 96 KB Flash holds a moderate code base — enough for a CAN gateway or sensor hub with a few protocol stacks, but not a full HMI with graphics. The 32 KB RAM supports a few kB of packet buffers and stack; watch the heap size if you are running multiple protocol layers.
Obsolete — sourcing through surplus channels
This part is marked obsolete by Texas Instruments. No official successor is listed in the Stellaris line. For BOM lines that require this exact order code, supply is available through independent distribution — sourced and quoted to order against an RFQ.
